David Simon
Chairman, Chief Executive Officer and President at Simon Property Group
Thank you. Pleased to report our second quarter results. Second quarter funds from operations were $1.1 billion or $2.96 per share prior to a non-cash unrealized loss of $0.05 from a mark-to-market in fair value of publicly held Securities.
Let me walk you through the big variances for this quarter compared to Q2 of 2021. Our domestic operations had an excellent quarter and contributed $0.13 of growth, driven by higher rental income of $0.09, strong performance in Simon brand ventures and short-term leasing of $0.05. TRG contributed $0.04 of growth, and they were partially offset by higher operating costs of approximately $0.05.
Our international operations posted strong results in the quarter and increased $0.10, lower interest rate or interest expense contributed $0.03. And these $0.26 of positive contributions were partially offset by the headwind from a strong U.S. dollar of $0.03 and $0.19 lower contribution from our other platform investments principally from JCPenney and a couple of brands within SPARC. These costs include -- these included costs associated with JCPenney's launch of new brands, the recent Reebok transaction and the integrated -- integration costs associated with that, and a softening of sales from our value oriented brands due to inflationary pressures on that consumer.
We generated $1.2 billion in free cash flow in the quarter, which was $200 million higher than the first quarter of this year, and we have generated $2.2 billion for the first six months of the year.
Domestic property NOI increased 3.6% year-over-year for the quarter and 5.6% for the first half of the year. Portfolio NOI, which includes our international properties grew 4.6% for the quarter and 6.7% for the first six months.
Occupancy at the end of the second quarter was 93.9%, an increase of 210 basis points and TRG was at 93.4%. The number of tenant terminations this year has been at record low levels.
Average base rent increased -- average base minimum rent increased for the third quarter in a row and was at $54.58. Leasing momentum accelerated across our portfolio. We signed nearly 1,300 leases for more than 4 million square feet in the quarter, have signed over 2,200 leases for more than 7 million square feet through the first half of the year. And we have a significant number of leases in our pipeline nearly 40% of our total leasing activity in the first six months of the year has been new deal volume. This is up approximately 25% from last year.
Retail sales continued. Mall sales volumes for the second quarter were up 7%. Our reported retailer sales per square foot reached another record in the second quarter at $746 per square foot for the malls and the outlets combined, which was an increase of 26%, $674 for the Mills, a 29% increase, TRG was at $1,068 dollars per square foot, a 35% increase.
We had began our national outlet shopping day, which was very successful for shoppers and participating retailers offering a timely first of its kind power shopping experience. More than three million shoppers visited our premium outlet and mills over the shopping weekend. Feedback following the event has been tremendous from both our retailers and consumers. We're already planning next year's event, which we expect to be bigger. So please stay tuned on that. Our occupancy cost at the end of the quarter are the lowest they've been in seven years 12.1% in Q2 of 2022.
Now, our other platform investments. Let's talk about it. We were pleased with the results of our investments in the platform for the second quarter. They contributed approximately $0.21 in FFO. Even though, we were down from last year's terrific results, primarily as I mentioned, continued investment and the inflationary pressures that have developed.
Based on our distributions, based upon our cash distributions received, we have no cash equity investment in SPARC and JCPenney. And in fact, we have parlayed our SPARC investment into our investment in AP -- in ABG, that is now worth over $1 billion. There will be a little more volatility from quarter-to-quarter when it comes to SPARC and JCPenney. But please keeping this in the proper perspective, it's all upside from here.
During the quarter, we also, as I mentioned, had our mark on our Soho and Lifetime Holdings of $0.05. A reminder on that, it's a non-cash mark, and we would expect that those, those companies would bounce back.
We completed the refinancing of 14 property mortgages during the first half of the year for a total of $1.6 billion at an average interest rate of 3.75%. We reduced our share of total indebtedness by more than $650 million. And once again, our balance sheet is strong. We have $8.5 billion of liquidity, $8.5 billion.
Today, we announced our dividend of $1.75 per share for the third quarter, a year-over-year increase of 17%. This will be payable at the end of the third quarter, September 30th. During the quarter, we repurchased 1.4 million shares of our common stock for $144 million.
And let me point out, while other companies in our sector are paying a little or no dividends and issuing equity, we are repeatedly raising our dividend and buying our stock back. We have now returned more than $37 billion of capital to our shareholders since we've been public, $37 billion.
Given our current view of the remainder of the year, we are increasing our full year 2022 comparable FFO guidance from $11.60 per share to $11.75 per share to the new range of $11.70 per share to $11.77 per share, which compares to a comparable number of last year of $11.44 per share. This is an increase of $0.10 at the bottom end of the range and $0.06 at the mid point of the range. The guidance comes in the face obviously of a strong U.S. dollar, rising interest rates and the inflationary pressures that are out there in the marketplace.
So let me conclude, I'm pleased with our second quarter results. Our business is strong with a higher income consumers in good shape. Brick and mortar stores are where the shoppers want to be outpacing e-commerce across the world and the broad retail spectrum demand for our space is extremely strong. Worldwide retailers need to grow, and they're doubling down on the U.S. International tourism is returning. Domestic tourism is strong.
Our redevelopment pipeline is growing with exciting projects, and our addition to our newly announced premium outlet new developments and expansions. We are experienced at managing our business through volatile periods, including leveraging our existing platform for operating efficiencies, allocating capital appropriately, managing risks. We are not over our skis in any aspect of our business. I encourage you look at our track record. We outperformed in these kinds of periods, and we also do some of our best work as well.
So thank you, operator. We're ready for any questions at this moment.
